' To all whomit may concern:

IOv

Beit known that I, SYDNEY I. PREsco'r'r, a citizen of the United States, residing at New York, in the county of New York and State of New York,'have invented a new and useful' Razor, of which the following is a specification. y I

This .invent-ion relates to an improvement v in razors, and one of the objects thereof is to provide a simple 'and efficientdevice in which a thin, replaceable blade is used and which can be used in the same manner as a razor of f vthe ordinary type.

IFS

A further object of the invention is to rovide a thin, fiat, detachable, double-e ged blade, the blade being stiH enough to retain a straight edge. j-

A further object of the invention is to provide a' device similar in form to an ordinary razor in which a'double safety guard is employed for the purpose of obviating the necessity of shifting the guard from one side of the blade to the other.

A further object .of the invention is to `provide a device which may be used either as a safety razor or as one 'of the ordinary type l with an exposed blade.

With these and other objects in view, the invention consists in certain constructions and combinations which will be hereinafter' 'fully described and then specifically pointed out in the claims hereunto appended.

In the drawings which form a part of\this specification and in which like characters of vreference indicate the same parts, Figure 1 is a plan view, vpartly in section, of a device 'embodying' the invention; Fig. 2 is a side elevation of the .structure shown in Fig. 1;

y Fig. `3 -is -an enlarged sectional elevation -side elevation of a part of the structure shown in Figs.` 1 and 2, illustrating #modi- V- iied formel.' clamp; Fig. 5 is an enlarged sectional elevation taken on the line 5--5 in Fig. 4; and Fig. is a detailed View of the blade.

In carrying the invention into effect,

there is provideda thin blade 1 which may be provided with two cutting edges 2, as

shown in Figs. 3and 6. The blade 1 is ilat,

and While being thin is'of sufficient thickness .to retain the cutting edges 2 in a straight line, thus avoiding ythe curling/of they edges 'flat clamp 7 is used, the clam which takes place when an excessively thin blade is used.

There is provided a support for the blade and this support 'may vary widely in struc'- ture. As shown, a support 3 is provided which is narrower 'than the blade and which extends throughout its length. extended from one end of the'support 3 and A shank 4'is' this shank 4 is pivoted at 5 to a handle 6 of any suitable structure. For the purpose of equalizing the weight and balancing the device the shank 4 lies in planes ilset from the planes of the support 3, and in' lanes coincident with the planes of the blagle, as is clearl shown in Fig. 1.

A c :imp is provided for securing the blade to the support and this clamp may nary widely in form. As shown, a substantial y being narrower than the blade and exten( ing through# out its length. The clamp iis provided with means engaging the support and having a limited sliding movement thereon to lock the blade'between the clam and support, and this means may vary wi ely in construction. In the best constructions and as shown, this means has a limited, longitudinal, sliding movement on the support and consists of a headed stud 8 which engages a shouldered countersunk slot 9 in the support 3 befoie referred to, the shoulder being cut away at one end of the slot, as is clearly shownin Figs. 2 and 4, so that the head of the stud ma be withdrawn from the support. jIt willfbe seen that the locking means is located between the exterior of the support and the exterior of the clamp. The b ade 1 is provided with erforations v10 and 11, the perforation 10 eing so located in the blade that theheaded stud 8 will pass through' it and into the slot 9 before referred to.

.position onthe support that the studs 12, en-

IOO

gaging the slots 13, Will prevent any rotating movement of the blade lon the stud S as a center.- i

Means are provided for protecting one edge ol the blade, when the other is to be exposed for use as in an ordinary razor. ln the modified form of clamp, illustrated in Figs. 4' and 5, this means consists of an extension 14 projected from one side of'the clamp 7. the edge of the extension being ribbed at 15, the rib extending over the edge ot the blade,

The device mayY be provided with means whereby it is converted into a safety razor and this means may vary widelyv in form. ln the best constructions and as shown, the clamp 7 is rovided with a. series of teeth lo projecting rom both sides ot the clamp and extending beyond the edge of the blade, as is clearly shown in Figs. .2 and 3. These teeth do not. contact with the cutting edges 2 of the blade.

Means are provided for protecting thc corners of the blade when the` double safety guard is used and this means is carried b v the clam and lies in the )lanes ofthe blade. In the t evice illustrated, this means eonsists of ribs 17 formed on the. end teeth projecting from the clamp 7, the ribs being bent to intersect the planes of the blade, as is clearly shown in Figs. 2 and 3. p

`Means are provided for assisting in the removal of a blade from the clamp and this means may vary in construction. I As shown, the clamp 7' is provided with arecess 1H at one end, the purpose ot this recess being to Yierinit the insertion of a tinger to litt the )lade from the clamp.

Changes and variations may be made in the structurc'by means of which the iiiveiition is carried ino ell'ect. The invention therefore is not. to bc restricted to thc precise structure shown and described.

What is claimed'isr" l. ln a razor, the combination with a llat detachable blade, of a support for the blade,

and a segregable clamp provided with a headed stud engaging a shouldered countersunk slot in the support and having a limited sliding movement inthe slot to lock the blade between the clamp and support, substantially as described.

3, 'In a razor, the combination with a flat detachable perforated blade,of a support for the blade, and a scgregable clamp provided with positioning studs passing through perfoi-ations of the blade and with a headed stud passing through one of the perforations of the blade and engaging a shouldered counter'- sunk slot in the support and having a limited sliding movement therein to look thc blade between the clam and thc support, substantiall)r as describe 4. In a razor, the combination with a flat detachable perforated blade, of a support for' the blade, and a segregablo clamp provided with positioning studs passing through and projecting bevond perforations ot the. blade and with a headed stud passing through a perforation of the blade and engaging a shouldered countersunk slot in the support and having a limited sliding movement therein to lock the blade between the alam and support the support being pro-l vider with elongated recesses engaged byy the projecting ends of the positioning studs, substantially as described.

5. In ay razor. the combination with a flat detachable blade, of a support for the blade, and a segregable clamp provided with blade positioning studs and with means engaging the support and havinir a limited sliding movement thereon to loc t the blade between the clamp and support the clamp being provided witli a linger recess, substantially as described.

6. in a razor. the combination with a tlat detachable double-edged perforated blade, ofa support for' the blade having a shank dieI tended from one end thereof the shank lying in'planes ofl`set from the planes of the support, and a. clamp provided with blade-positioning studs passing through and projecting beyond pcrforations of the blade and with a headed stud engaging a shouldered counter sunk slot in the support and having a limited sliding niotf'emciit thereon to loclt the blade between thc clamp and support thc opposite edges of the clamp being provided with teeth to form a double safctiY guard and the corner teeth being bent to intersect the planes of the blade to protect the corners thereof. sillistantially as described.

7 ln a razor, the combination with a. perforated blade, of a support for the blade, a clamp, incans for positioning the blade between the support and clamp, independent means passing through the blade for holding thc su )port and clamp together, and a shank extended from ont` end of the support and living in planes co-incident with/the planes of tbe blade, substantially as described.

ln testimony whereof, l have signed niv naine to this specification in the presence of two subscribing witnesses.
